Walking with Monsters: Water Dwellers

Petrolacosaurus was a primitive reptile from the Carboniferous. It was one of the earliest reptiles to evolve.

Physical appearance and biologyEdit

Petrolacosaurus was a small reptile. It had the body shape similar to a modern day lizard, like the slender body and splayed out limbs. It also had a row of bumps and knobs running down its back. It was green with white patterns and had a shade of red around its eyes.

Behaviour and traitsEdit

Petrolacosaurus was a small diapsid which was 40 centimetres long. This reptile was a carnivore which mainly fed on small insects, arthropods and maybe even the corpses of large animals like Mesothelae spiders.

Once it hatched from its eggs, Petrolacosaurus would be completely independent. Living on their own, they were vulnerable to attack from the supersized arthropods around during the Carboniferous. However, it was a relatively fast animal so it could outrun its pursuers.

In Walking with MonstersEdit

Water DwellersEdit

A nest of Petrolacosaurus eggs hatched and they climbed out of their eggs. However, a Mesothelae spider crawled up to the nest and attacked and presumably killed most of them.

Reptile's BeginningsEdit

A Petrolacosaurus approached a Mesothelae burrow. However, the resident Mesothelae emerged from its headquarters and chased the reptile. Fortunately for the Petrolacosaurus, it hid inside a fallen log. Despite that, the Mesothelae managed to break through the roof of the log and attacked and killed the Petrolacosaurus. The corpse was then dragged back to the Mesothelae burrow which had now flooded.

When the Mesothelae was searching for a new burrow, a Petrolacosaurus was evicted by the spider, despite the fact that Petrolacosaurus didn't require burrows.

After a storm passed, a Petrolacosaurus approached the new Mesothelae burrow and entered inside. It came out dragging a fried Mesothelae corpse which was struck by a lightning bolt. The reptile then fed on a spider barbeque.
